Keyboard illumination system

1. A keyboard illumination system, comprising: an electronic device having a keyboard with at least one keycap, the at least one keycap having disposed thereon at least two different legends, at least one of the two different legends visible in response to being illuminated with an ultraviolet (UV) light source, the electronic device configured to register input of the at least one legend while the UV light source is activated, wherein the UV light source is removable from the electronic device and directionally adjustable by a user for directing energy toward the keyboard.

2. The system of claim 1 , wherein the at least one legend is imprinted on the at least one keycap using a fluorescent colorant.

3. The system of claim 1 , wherein the at least one legend is imprinted on the at least one keycap using a luminous colorant.

4. The system of claim 1 , wherein the at least one legend is formed on the at least one keycap to be invisible under white light.

5. The system of claim 1 , wherein the electronic device comprises a notebook computer, and wherein the UV light source is disposed in a display member of the notebook computer.

6. The system of claim 1 , wherein UV light from the UV light source is directed toward an underside of the at least one keycap.

7. The system of claim 1 , wherein the electronic device comprises a notebook computer.

8. The system of claim 1 , wherein the UV light source comprises at least one light emitting diode (LED).

9. A method for manufacturing keyboard illumination system, comprising: providing an electronic device having a keyboard, the keyboard having at least one keycap with at least two different legends disposed thereon, at least one of the two different legends visible in response to being illuminated with an ultraviolet (UV) light source; and configuring the electronic device to register input of the at least one legend while the UV light source is activated, wherein the UV light source is removable from the electronic device and directionally adjustable by a user for directing energy toward the keyboard.

10. The method of claim 9 , further comprising imprinting the at least one legend on the at least one keycap using a fluorescent colorant.

11. The method of claim 9 , further comprising imprinting the at least one legend on the at least one keycap using a luminous colorant.

12. The method of claim 9 , further comprising forming the at least one legend on the at least one keycap to be invisible under white light.

13. The method of claim 9 , further comprising: disposing the keyboard in a notebook computer; and disposing the UV light source in a display member of the notebook computer.

14. The method of claim 9 , further comprising directing UV light from the UV light source toward an underside of the at least one keycap.

15. The method of claim 9 , further comprising configuring the UV light source as at least one light emitting diode (LED).

16. A keyboard, comprising: a plurality of keycaps, at least one of the plurality of keycaps comprising a first legend and a second legend where the second legend is different from the first legend, wherein the first legend is visible in white light, and wherein the second legend is invisible in white light and visible in ultraviolet (UV) light; and a lightpipe base plate formed of optically transmissive material to facilitate light transmission therethrough, the lightpipe base plate receives the UV light from plural light sources and directs the UV light upwardly toward an underside of the plurality of keycaps to illuminate light-transmissive portions corresponding to second legends on the plurality of keycaps.

17. The keyboard of claim 16 , wherein the second legend is imprinted on the at least one keycap using a fluorescent colorant.

18. The keyboard of claim 16 , wherein the second legend is imprinted on the at least one keycap using a luminous colorant.

19. The keyboard of claim 16 , wherein the keycap is formed to enable the UV light to be directed toward an underside of the at least one keycap to illuminate the second legend.
